City of Green, Kansas Nitrate Reduction

City of Green, Kansas Nitrate Reduction

In September 2012, AdEdge Water Technologies, LLC participated and was awarded a Contract managed by BG Consultants for the equipment pre-selection of a nitrate removal treatment system for the City of Green, Kansas. The scope of the contract included the design, manufacture, and startup of the treatment system. The City of Green is a small community of approximately 125 residents located in northeast Kansas. Water testing revealed a sustained nitrate level of 12 mg/L as N. The United States EPA has set the maximum contaminant level at 10 mg/L NO3-N in drinking water. The town receives water from four wells which alternate in operation. The AdEdge treatment system was designed to treat 40 gallons per minute and to remove up to a maximum of 25 mg/L of NO3-N (as required by the Contract). The treatment system was packaged in a compact, skid-mounted unit, model APUIX-NO3-2472CO-3-290, utilizing three vessels arranged in parallel, each loaded with AdEdge ADIX-NO3 nitrate-selective anion exchange resin. Two of the vessels are always maintained in service, while the third vessel is offline in regeneration or in standby. The resin is supplied in the chloride form as moist, tough, uniform spherical beads and is NSF 61 certified. AdEdge Treatment System Features
